Hi Mike,


split() can't, but splitlines() can.

###
>>> s = "hello world\nthis is a test\n"
>>> s.split()
['hello', 'world', 'this', 'is', 'a', 'test']
>>> s.splitlines()
['hello world', 'this is a test']
>>> s.splitlines(True)
['hello world\n', 'this is a test\n']
###

splitlines() can take in an optional 'keepends' parameter: if we send it a
true value, then it'll keep the newlines.


We can find out more about the string methods in the Library Reference:

I hope this helps!
